Why FEG?

Hi,
I've been playing around with Max Sidorow's CTFexplorer and I'm finding
it hard to see the
advantage of FEG microscopes for structural biology.
At 61000-times magnification I can't see any major difference between
the Tecnai 20T and
the Tecnai F20T for example.
Only at magnifications beyond 300000 is the F20T clearly superior (due
to better spatial
coherence).
Am I (or is CTFexplorer) missing something relevant?
The CTFexplorer can be found at http://clik.to/ctfexplorer.
Upon request I can also send a Word file with the CTF-plots.
Philip
